the legs pale; head nearly as long as wide, suborbicular, finely punctured, the 

 eyes very large, finely faceted, convex, at less than half their length from the 

 base, the tempora rapidly rounding and less prominent; antennae very short, 

 rapidly and very strongly incrassate, pale flavo-testaceous, with the outer 

 four joints abruptly dark brownish-piceous, the first joint oval, twice as long 

 as wide, not longer but stouter than the second, which is much elongated 

 and distinctly longer than the third, fourth to tenth transverse and rapidly in- 

 creasing, the tenth two and one-half times as wide as long, the last very obtuse 

 and as long as the two preceding, the erect sparse setse not conspicuous and 

 rather short; prothorax large, convex, transverse, much rounded at base, 

 with the sides converging and moderately arcuate, more so apically, much 

 wider than the head, as wide as the elytral base but narrower than the apex, 

 unimpressed; elytra large, moderately transverse, with diverging sides, the 

 apical sinuses very feeble, the suture fully one-half longer than the prothorax; 

 abdomen short, gradually and strongly tapering throughout, at base almost 

 as wide as the elytra. Length 1.4 mm. ; width 0.44 mm. Virginia (Norfolk). 



Peculiar in its short fusoid form, large eyes and elytra and short, 

 rapidly very incrassate, bicolored antennae. 



Dolosota (Microlia) petulans n. sp. Less fusoid, rather convex, shining, 

 the punctures not at all asperate, minute, not close, somewhat coarse on 

 the elytra, the abdominal reticulation finer, nearly obsolete and more trans- 

 versely arranged; body pale luteo-flavate, the head and elytra somewhat 

 darker, the latter broadly paler basally and more silvery in lustre than the 

 anterior parts, the abdomen with a smaller and feeble subapical cloud; 

 head much more transverse, the eyes not so prominent and at one-half their 

 length from the base, the caringe strong and entire; antennas as in the pre- 

 ceding but larger and longer, infuscate, gradually pale basally, the outer 

 joints similarly transverse but the last larger and of very different shape, 

 being acutely conical from near the base and much longer than the two pre- 

 ceding; prothorax similar in form but much less greatly wider than the head, 

 the latter being larger; elytra similarly only moderately abbreviated but 

 narrower and with rather less diverging sides, the outer sinuses at apex 

 somewhat narrow and evident, the suture about one-half longer than the 

 prothorax; abdomen narrower, gradually but rather less strongly tapering 

 throughout and at base distinctly narrower than the elytra, the side margins 

 apparently thinner. Length 1.38 mm.; width 0.38 mm. New Jersey. 



Male sexual characters are not observable, either in this or the 

 preceding, and are probably very feeble as in Dolosota. Petulans is 

 distinguishable from pernix by its narrower form, smaller eyes and 

 larger antennae, which are of different coloration and with the last 

 joint conical. 



Aremia n. subgen. 



In this group, which I think really has a greater value than the 

 subgenus, the sterna between the middle coxae offer a peculiarity
